The Role of Receptor-Like Kinases in Regulating Cell Wall Function1
... Single loss-of-function mutations in THE1 in an otherwise wild-type background did not result in any detectable change in plant growth and development (Hematy et al., 2007), suggesting that THE1 function is only revealed when the cell wall is perturbed. However, recent studies have shown that THE1 i ...
